Doctors have long used injections of human growth hormone to treat children who are short because of abnormally low levels of this growth-stimulating substance. But now, a decade-long study led by a Stanford researcher shows that the same treatment also stimulates growth in short but healthy children.
Hummingbirds' ability to learn from their environment saves them from suffering the costs of severe competition and may-just may-increase the number of species which potentially might coexist in a given habitat, an ecologist from The University of Arizona has discovered.
New photos from the Mars Global Surveyor show that horizontal layers extend deep into the canyons of Mars. The structure and composition of the layers suggest that volcanic activity played a far greater role in the early geology of the Red Planet than previously believed.
For three decades social scientists have had little success in figuring out how a person's race affects the outcomes of crimnal cases. Now University of Washington researchers have found that court reports prepared prior to sentencing by probation officers consistenly portray black and white juvenile offenders differently, leading to harsher sentencing recommendations for blacks.

The researchers gave the drug oltipraz, originally developed to treat schistosomiasis, to a group of people at high risk for developing liver cancer. The oltipraz changed the way in which the study group metabolized aflatoxin, a liver carcinogen produced by a fungus that contaminates foods like corn and peanuts.

Flipping a nano-scale molecular switch may regulate cell-binding in a protein involved in healing and other biological activities. Computer simulations show that, like untying a shoelace, tugging on a strand of the protein fibronectin unravels a loop critical to cell recognition but allows the protein to easily reassemble.

Results of a study published in the February 16 issue of the Annals of Internal Medicine suggest that in the near future a simple blood test to detect levels of sex hormones could predict which women are at the highest risk of developing breast cancer.
Scientists at NYU School of Medicine and The Rockefeller University have discovered the structure of a key compound that enables a dangerous bug to cause devastating infections. They have also designed molecules that block the compound's effects, opening a novel way to combat these infections.
Scientists know more about why we start eating than why we stop. Some clues, however, are starting to emerge on "satiety factors", in other words, the signals that tell your brain when it's time to push away from the dinner table.
As the nation struggles with its current crises in food safety and consumer confidence, MSU experts are ready to discuss safety across the food chain - from farm to family.

One of Mother Nature's most important talents is the ability to distinguish one molecule from another. Like locks accepting keys, proteins function by being able to let one particularly shaped molecule inside while barring other shapes from entering.
Most schoolchildren have at least an annual relationship with museums: their end-of-the-year class field trip. For some Illinois children, that relationship is about to intensify, and eventually the same will be true for kids around the country.
Joblessness, not race, is the key predictor of all forms of violent death -- homicide, accidental death and suicide -- according to a study by University of Washington demographers who looked at census data and vital records for Chicago. They also found the average life expectancy for poor black males dropped by 1 1/2 years between 1970 and 1990.
